List of Wild Kratts episodes

At the Nile River, zoologists Chris and Martin Kratt are on a mission to show one of their fellow Wild Kratts team members—brilliant young inventor Aviva Corcovado—that there's more to crocodiles than just violence and snapping jaws. After shrinking themselves down to a few inches tall by using Aviva's Miniaturizer invention, the Kratt brothers disguise themselves as crocodile eggs and sneak into a mother crocodile's new nest. In the Wild Kratts team's turtle-shaped aircraft and headquarters—the Tortuga, one of Aviva's greatest inventions—the Wild Kratts tech team, consisting of Aviva, communications expert and mechanic Koki, and skilled pilot Jimmy Z monitor Chris and Martin and watch as the mother crocodile faithfully guards her nest against predators for months without even eating anything. Eventually, as the crocodile eggs hatch and the crocodile mom uses her mouth to carry several of her newly hatched babies to the river, Aviva changes her mind about crocodiles and decides that these reptiles are in fact caring and dedicated mothers. But when the mother crocodile leaves the river to go get more hatchlings from her nest, predators threaten the first batch of baby crocodiles. The Kratt brothers must use the incredible Creature Power Suits—two of Aviva's inventions—to gain the abilities of crocodiles and protect the vulnerable crocodile hatchlings.

The Kratt brothers use Aviva's amphipod-inspired submersible, the Amphisub, to dive into the deep waters of the Southern Ocean. There, they witness a never-before-seen wildlife moment: a battle between a sperm whale and a giant squid. However, the water pressure at the extreme depths where the battle is taking place badly damages and partially crushes the Amphisub, forcing Aviva to use her new ExtendoArm invention to pull the submersible back to the Tortuga. To allow Chris and Martin to return to the site of the whale-versus-squid battle, Aviva programs two new Creature Power Suits—Sperm Whale Power for Chris, and Squid Power for Martin. The Kratt brothers use their new Creature Powers to dive back into the deep sea, where the sperm whale and the giant squid are still locked in combat. Suddenly, the sperm whale becomes entangled in a discarded fishing net and begins sinking toward an area full of underwater volcanoes. To make matters worse, a colossal squid attacks the sperm whale's calf. Chris and Martin must put their Creature Powers of both sperm whale and squid to good use to rescue the mother sperm whale and her calf.

The Wild Kratts crew travels to Mozambique's Savanna to create a geological map of all the local aardvark dens, hoping to study the secrets of the rarely seen aardvark. But after a young aardvark accidentally becomes a stowaway in Chris' backpack, the team set off on a search to return him to his home burrow, and find his mother. Along the way, they discover how aardvarks manipulate earth materials to alter landscapes and learn the incredible (and valuable) service this amazing animal provides to all burrow-living creatures of Africa. But after searching hole after hole, the Kratt brothers discover that the aardvark's mother and the other burrowing animals have been kidnapped by the evil inventor, Zach Varmitech, who plans to use the aardvark to dig his pool for him. They manage to stop Zach and return the mama aardvark to "Slurpy" while Zach has a run-in with an angry warthog.

They then spend the day with an earthworm named Pinky, tunneling underground, and observing the everyday life of a worm. But after their new worm friend is carried off by a bird and left on the sidewalk to die, Chris and Martin race to save the worm before the sun dehydrates her.

While kayaking in a tributary of Australia's Murray River, Chris and Martin find a mother platypus and her eggs, and shrink down to watch them hatch. But when the evil endangered species Chef Gourmand floods the platypus's den and steals the platypus eggs, and kidnaps Chris as a side dish, Martin and Aviva work around the clock to solve the mystery of the platypus' sixth sense with the Kratts' new platypus friend.
